Patented April 7, loos.

Application filed October H ZEiW. Serial No. 388,508.

To all whom it may Be it known that I, Senor; ScHMw-Roosr, a citizen of the Republic of Switzerland, residing at Oerlikon, near Zurich, in Switzerland, have invented certain new and useful Improvements in Ball-Bearings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawin s', and to letters or figures of reference mar (ed. thereon, which form a part of this specification. I y

The subject of my inyentionyis a ball bearing having two. concentric bearing rin s,

grooved to present a raceway io'rtheha s, y

and inclosing a spacing device for the balls between them.

The spacing device consists of twin rings of rectangular section, having vebs that lie at right angles to the axis of the bearing detachably connected together. {lhe' spacing" rings are notched to form recesses between the Webs for the reception of the hails in. such manner that when the balls, are inserted in the recesses they are held at definite distances apart by the webs. 1

The two concentric hearina each provided at one edge with a depression coniinunicating with the raceway but not as deep as the latter, through which the balls can be introduced between the rings Without the latter havin as hitherto, to he displaced eccentrica lly to each other in the same lane as it is only necessary to incline one ot the rinse laterally, Without, however, eccentrically displaciin it, so that the coinaiding depressions of t .e two collars present a s ace longer than the diameter of the balls.

ne form of construction of the new bearing is illustrated in the accompa'nying dravh in in which, i

l igure l is an elevation. Fig. 2 a vertical cross section of the bearing-rings and ballspacing; device in o'oeretive position.

opposed-faces wit 'grooves'c constituting a raceway for the balls cl. in cross section the nt'ceway presents a flatter curve than the peripheries of the halls contained therein, the purpose of which will; be hereinafter set forth. The ball-spacer comprises twin rings .60

f and 9 (Figs. 3 and-4) having Wchsf, 7' respectively, formed on the peri hery of the rings at their inner ed 'es, seir inner edges having notches 7c formed therein between the webs. When placed in position between the hearing-rings the Webs are connected b screws or bolts'h. Theedges of the webs and notches are curved as shown at Lllig. 3-,

and constitute a partial c' lindrical casing,

the axis a of r'hich passes t tough the center oi aballj held thereinand lies parallel to the axis 0 of the rings f, g.

in order that the balls 12 ma he placed in the raceway Without displacing the rings cccentric'aily, I rovide" a notch 11 in one edge the halls escepingthrou "h thefnotch'es, said notches are of less dejifii forming the raceway. As the perpendicular diameter of the raceway is substantiall the same as the diameter oi the halls, the diameter of the opening formed hythe notches is less than the diameter of the balls.

' oieach ring, 4 in order to preveht liability of 7 than the grooves To insert the halls in the racewey through V the opening formed by the notches, said notches are brought opposite each other as shown in high; but, as above stated, the opening is'srnaller in diameter than the balls and to permit the passages of the halls through theopening the latter is enlarged as shown in Fi' 5. To permit of such lateral movement w en a number of balls are in the raceway, the curveof the grooves formin the raceway is made flatter than the curve 0 the periphery of the balls.

After the re uisite number of balls have i tric hearing rings groove to form a raceway,
